Sizes and Use

All of our setting plug gages are available in inch and metric sizes up to 16.25" diameter (412.75mm). Truncated setting plugs are distinguishable by the smaller major diameter of the first half of the threads. When using the truncated setting plug, set the ring gage on the full form portion before threading it onto the truncated portion. If the ring gage shakes at all on the truncation, it is no longer gaging correctly and should be replaced or reconditioned by relapping.

Thread Styles

The set plug gages are offered with unified 60 degree, 60 degree Stub, ACME, Stub ACME, NPSM, UN, UNS, BUTTRESS, or Trapezoidal threads from a coarse pitch of 2 TPI to a fine pitch of 40 TPI. Left hand threads are available.

Handles

Based on size, our GO and NOGO plug gages are available in reversible, taperlock, trilock, and ball handle styles.

Pre-Plate

If you need pre-plate set plugs, we can make them to your specifications. Do not hesitate to call or email us.
